Image quality of the Sony 85mm f2.8 SAM

Before starting, it is worth noting that a lot of prime 85mm lenses have already been measured on DxOMark.

We last reviewed the Samyang 85mm f/1.4 Aspherical IF Nikon and Canon Mount and it did not perform as well as the best lenses from this category, such as the Sony Planar T* 85mm F1.4 ZA or the Canon EF 85mm f/1.8 USM, for example. The Sony 85mm f/2.8 is about the same price as the Samyang lenses, but it does not perform as well. Nevertheless, it has an autofocus feature which the Samyang lacks.

It achieves a DxOMark score of only 15 (most of the other 85mm primes got more than 20 points on full-frame cameras).
On the other hand, the Sony 85mm f2.8 SAM’s resolution metrics are as good as those for the lowest resolved 85 mm lenses, such as the Samyang 85mm f/1.4 Aspherique IF Canon (52 lp.mm; for comparison, the other 85mm lenses achieve a resolution metric between 57 and 67 lp.mm)
